Hello, Andy from the Data Working Group here.
There are lots of these. For those who may be unfamiliar, “rumah” just means “house”. A large concentration of them are here.
Perhaps someone could get in touch with them in their own language to explain who these might be mapped better?

Thanks - obviously tidying up obviously wrong data makes sense. However, what will stop new ones being created is someone taking the problem mappers under their wing and explaining what needs to change.
Hi Andy, thanks for pointing out. I sent a message to him here (Changeset: 155535557 | OpenStreetMap). Thanks @ivanbranco for sharing the link
